• ketuḥ — the (chariot's) flag / banner
  Ketu = banner. The highest visible point of a moving chariot. The gopīs watch the flag because the body of the chariot has already vanished — they cling to the last detail of His departure.
• reṇuḥ — the dust
  Reṇu = the dust raised by chariot-wheels. When even the flag passes from sight, only the dust marks His passage. Gauḍīyas note that this very dust later becomes their object of worship — the dust of His chariot's road is itself tīrtha.
• lekhyāni iva — like figures in a painting
  Lekhya = a painted figure (from √likh, to scratch/draw). Their bodies have become still as paint on wood. The metaphor anticipates the iconographic immobility of devotional images themselves — the gopī sitting as a mūrti.
• anuprasthāpita - ātmānaḥ — having sent their souls after (Him)
  The mind/soul (ātman) is sent ahead with the chariot. The body remains but is empty — only a shell, awaiting return. Gauḍīya doctrine: the devotee's ātman lives where the Lord is, not where the body sits.

Like a row of paintings whose subjects have sent their souls after the disappearing chariot — the gopīs stand as still as figures on a wall, watching first the chariot's flag and then merely the dust raised by its wheels. When even the dust settles, they themselves become the dust.
